SPECIFICATION forming part of Letters Patent No. 530,620, dat d December11, 1894.

Application filed August 1, 1894. Serial No. 519,187. (No model.)

.To all whom it may concern:

Be it known that I, THOMAS MAHER,a citizen of the United States,residing at Cleveland, in the county of Cuyahoga and State of Ohio, haveinvented certain new and useful Improvements in Lawn-Sprinklers, ofwhich the following is a full, clear, and exact description. a

My invention consists of a case having within it an annular chamber withan opening oroutlet at the top, a post rising from the center of thefloor of said chamber, and an external extension projected from thewallof said chamber and 0d of the center, with a threaded openingtherein for the attachment .of a hose, said extension opening into theinthrough the sprinkler naturally varies in ex-' tent, according to theamount of water permitted 'to enter the same and the pressure behindsaid water, so that a large or small surface of spray may be obtained byregulating the flow of-liquid through the hose as desired.

That my invention may beseen and fully understood by others, referencewill be had to the following specification and annexed drawings forminga part thereof, in which- Figure 1 is a side view of my sprinkler;

j Fig. 2, a front view of the same Fig. 3, a vertical section on'linesx, as, Fig.0; Fig. 4, a similar section showing a modified form of post;Fig. 5, a plan View of said sprinkler, and Fig. 6, a horizontal sectionon lines 3 y, Fig. 1. V

Similar figures of reference designate like parts in the drawingsandspecification.

The case 1 is constructed of iron, glass, porcelain, or other suitablematerial and consists of the flange 2, the floor 3, the cylindrical wall4, the oval top 5, and the'extension 6.

The external shape of the case 1 mayvary from that shown in thedrawings, provided Directly above representing the horizontal center ofthe extension considerably in advance of or remote from a parallellinepassing through the center of the chamber 7. In the forward end.

of theextension 6 is the threaded opening 10 to receive the end of ahose or other supply pipe, and said opening terminates atthe back in thecontracted orifice 11, close to the tangent side of said extension.

In operation the case 1 is connected to a supply pipe by means of theextension 6, and placed on the ground in the locality which it isdesired to sprinkle, the flange 2 assisting to retain said base in anupright posit-ion, or it may be held in the handto spray vines and otherforms of vegetation that have a more extensive vertical growth thangrass and the like. The water is turned on, enters the chamber 7 throughthe extension 6 with great force owing to the fact that the orificell isso much smaller than the extension opening 10, passes around saidchamber in the direction of the arrows in Fig. 5, encounters theincoming stream, and then escapes through the hole 9 in the formofspray. Theimpact of the water in the chamber 7causes thesame to leavethecase l in the formof spray which spreads out. umbrella-like, limitedin extent only by the force or pressure behindthe fluid. The taperingpost 8 serves as a pivot around which the water passes andsaid postfurther directs the upward rush of the same toward the hole 9. The post8 is not an absolutely essential member of myinvention', but betterresults are produced by its use. I

In Fig. 4 a modified form of the post8 is shown at 8*,in which appearthe vertical passage 12 and the lateral passages 13 at or near the baseof said post, opening into said vertical passage at the bottom of thesame. The

post 8 is threaded at the base and screwed into a. threaded opening in.the floor 3. By

using the perforated post 8, a portion of the water entering the chamber7 is forced into.

the passages 13 and escapes through the central passage 12 in anunbroken stream, about which the spray from the balance of said water isdisseminated.

What I claim as my invention, and desire to secure by Letters Patent, is

As a new article of manufacture, a sprinkler consisting of a case havingwithin it an annular chamber opening through the top of said case, acentral post rising from the floor of said chamber and provided withlateral, basic passages opening into a vertical passage in said post,and an external extension pro- THOMAS MAHER.
